EVIL1 Posted October 5, 2008 Report Share Posted October 5, 2008 Spark blow out. What are your plugs gapped at? You may need a better ignition if you don't already have it. Quote Link to comment Share on other sites More sharing options...

Guest Hal Posted October 5, 2008 Report Share Posted October 5, 2008 I would say the plugs are the issue. What plugs are you running, and what gap? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted October 5, 2008 Report Share Posted October 5, 2008 auto lite 24's, gap at .040. car worked flawless for me. but then i only did 2 pass's on it. both being 2nd threw 4th gear. im thinking maybe one the the noids are actting up and not shotting(im thinking spray one).

EVIL1 Posted October 5, 2008 Report Share Posted October 5, 2008 Try the simple things first. I would get new plugs and gap them at .030 and see if that helps. Quote Link to comment Share on other sites More sharing options...
Hwilli1647545487 Posted October 5, 2008 Report Share Posted October 5, 2008 My guess would be ignition issues (spark blowout), or too much fuel as has been said. I can stop over and help you sometime this week if you want. Quote Link to comment Share on other sites More sharing options...
88lx5oh Posted October 5, 2008 Author Report Share Posted October 5, 2008 im running an MSD 6AL and blaster 2 coil, autolite 24s.. i think it seems to be a too much fuel issue.. i think that is what me and Josh were figuring at the track.. butt now i dont know, hence why im here for suggestions Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted October 5, 2008 Report Share Posted October 5, 2008 make sure the n20 is coming threw the noid. take the hose off the plate turn the bottle on and bring the motor up on the switch then hit the micro. at the same time take the fuel hose and stick it a fuel jug. this way you can make sure you are getting both! these are the hoses coming off the noid! if the n20 side is not shooting much you'll know it. just dont spray yourself with it!

88lx5oh Posted October 5, 2008 Author Report Share Posted October 5, 2008 im pretty sure the n20 side is spraying.. i went through almost a bottle playing around with it Quote Link to comment Share on other sites More sharing options...
flippy1974 Posted October 6, 2008 Report Share Posted October 6, 2008 spark plugs need to be at 30-35 and 1 step colder than stock and check your n2o filter and when u check n2o flow use a rag to hold the hose and hold it on for about 5 sec blowing in the air to see ifit dies off any.

Guest 614Streets Posted October 6, 2008 Report Share Posted October 6, 2008 Just want to say that If its a too much fuel issue, that I did not see black smoke from your car at the track. I honestly can't say anything with out seeing it first hand. You mentioned at the track that you were running a dead head regulator and that it was creeping up on you to high psi. I wasn't quite sure what you meant when you said high psi at the regulator. I do remember its a 650 holley dp and carb psi Quote Link to comment Share on other sites More sharing options...

Guest 614Streets Posted October 6, 2008 Report Share Posted October 6, 2008 Hoblick any chance you have a picture of your set up , regulator , gauge type etc. Quote Link to comment Share on other sites More sharing options...
88lx5oh Posted October 6, 2008 Author Report Share Posted October 6, 2008 umm i can dig a pic up sometime tonight. its the basic holley chrom reg. i think its like the 12803 or sumthing Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted October 6, 2008 Report Share Posted October 6, 2008 The thing is it shouldn't spike pressure up on the outlet of the dead head regulator to anything except where it is set , 6psi for example. Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted October 6, 2008 Report Share Posted October 6, 2008 basiclly. his setup was like mine. only thing is he has one pump. the feed line up to the front y's off to both reg's. one feeds the carb the other feeds the spray. but his gauges are off the side of the reg thats not being used. my gauges came right off the spray noid, and the carb. even when i had one pump running both, i never had issue with the fuel side creeping up like that. im still tryying to figure out how it was working fine for me, then is breaking up bad for him...only diffence was i hit it with the 25's in it on 100, then changed to the 24's and tweeked the carb up some . i never tryyed it after that.

Guest 614Streets Posted October 6, 2008 Report Share Posted October 6, 2008 Gauges shouldnt be on the side not being used. Quote Link to comment Share on other sites More sharing options...
88lx5oh Posted October 6, 2008 Author Report Share Posted October 6, 2008 i can try teeing off the fuel noid for my gauge (rob got an automoter in the cowl installed now) me and josh even tried running just one reg, and had the gauge ran off the carb log... pressure stil creeps with the motor off and pump kicked on. and still broke up on the bottle. im frustrated and havent touched the car since i brought it home. need to take a week off from it. someone else said the noids may be to big... any ideas there??

Guest Removed Posted October 6, 2008 Report Share Posted October 6, 2008 Gauges shouldnt be on the side not being used. his carb side seems to be working fine like that. and i think it was mounted that way when he got it. the y at his carb has the fitting for it, and it should be tapped there. and the other right at the noid. but not much room there. should be ok at the other end. i was thinking of that when i had it here, but didnt have the fitting i needed to change it. plus it was like 11:30 and the hood was bitching they was tryying to sleep while im in the driveway revving his car setting timing and what not Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted October 6, 2008 Report Share Posted October 6, 2008 someone else said the noids may be to big... any ideas there?? thats not going to be a issue. the jet is what keeps the fuel at bay. i just need to tinker with it one day, for a whole day instead of just a few LATE hours here and there.

I was going to reply I have a set you can borrow to see if your noids are too big vs the shot , but one thing at a time. I have 2 sets of the tight small noids, better for 100-125! But like rob said that has nothing to do with additional fuel , however they do deliver faster and crisper when the shot is 75-125! Dude my s10 was a complete handful just bringing it to the track , don't give up or get too frustrated these things ALWAYS come up. Always.

Guest 614Streets Posted October 6, 2008 Report Share Posted October 6, 2008 Fuel makes the power I say its not getting enough psi on the other side!? Quote Link to comment Share on other sites More sharing options...
